Answer:

x = 126

Step-by-step explanation:

-\frac{2}{7}x - \frac{8}{21}x + \frac{1}{3}x = -42

-\frac{2}{7}x (multiply numerator and denominator by 3)

-\frac{6}{21}x

\frac{1}{3}x (multiply numerator and denominator by 7)

\frac{7}{21}x

-\frac{6}{21}x - \frac{8}{21}x + \frac{7}{21}x = -42

-\frac{7}{21}x = -42 (multiply everything by -21)

7x = 882 (divide everything by 7)

Convert 3/8 to a decimal and percent but pls explain how you guys get 375 pls ;-;
natali 33 [55]
You just divide 3 by 8. when 3 is inside the "house" and 8 is outside, 8 doesn't go into 3 so move on and 8 goes into 30 3 times. and so forth. 30-24=6 bring down the 0. 8 goes into 60 7 times. the decimal is 0.375. the percent is 37.5%.

I need to solve the equation 6n + 21 = - 3 - 2n
Kaylis [27]

Answer:

n= -3

Step-by-step explanation:

First, your're going to subtract from both sides

6n + 21 - 2 1= -3 - 2n - 21

Then simplify

6n = -2n - 24

Then add 2n on both sides

6n + 2n = -2n -24 + 2n

Simplify again

8n = -24

Then divide both sides by 8

8n/8 = -24/8

Then simplify and this is your answer

n= -3
